2011 January SAT: Math

<p>kcikatAZ, can you please explain that question. I have no idea what the math questions mean when they remainder. I am absolutely appalling at SAT math.</p>

<p>If you’re referring to the problem I think you are, the answer was 16.</p>

<p>x + y = z
z = 8
What does x + y + z equal?</p>

<p>^^That was the x y z question I remember.</p>

<p>That was in the multiple choice section, I’m talking about the open-ended section in section 2 (?) I had 16 though for MC.</p>

<p>@Tenors </p>

<p>Oh, ok. I remember having two answers as “4” (I think separated by one question) in the write-in but I don’t remember the question that wasn’t the remainders.</p>

<p>Remainder as in, when I divide by 10, I have 6 left over. What I did for this problem was just use the number 16 (as you see, there’s 6 left) and 18. 16 + 18 is 34. When you divide that by 10, you have 4 left over, the answer.</p>

<p>when ever you divide by 10 u the remainder is the ones digit, so since the remainders were 6 and 8 you can just add them together to get 14, and the ones digit in that is 4.</p>

<p>Interficio,
I’ve seen that you have said you had a lot of problems with these math problems. If it helps, you can fill in the variable they give you with a random number that fits the conditions. For example, for the remainder question, pick 106 and 108. They both fit the description. Then, when you add them to create 214, it has a remainder of 4.</p>

<p>I missed one… FUUUuuuu</p>

<p>2 wrong 1 omitted would be about what?</p>

<p>thanks, GS! I did try the filling in number strategy but I’m unfamiliar with the wording of the question. I haven’t been asked anything about remainders since like 4th grade… I understand it now… what a shame I couldn’t answer such an easy question but at least I omitted it.</p>

<p>can someone tell me what the knitting question was asking? i had a math exp but i don’t remember it lol</p>

<p>I think the answer is 5200 but not 5700,because the curve is decreasing.
If anyone learn calculus,the second derivative is negative;thus the answer has to be less than 5500 but not greater 5500…</p>

<p>= =,actually i am not sure about this one too…</p>

<p>^
The graph was increasing, not decreasing</p>

<p>the curve is definitely decreasing.
The problem is not talking about which one is the closets;it’s talking about below the 5500~~~</p>

<p>lol don’t try to justify like its the ap calc BC exam. It was a bit over 5500 and so it was 5700.</p>

<p>I definitely had a graph that was increasing. Could we be looking at different problems here?</p>

<p>@rover112</p>

<p>The graph was increasing, its slope was decreasing. But that has no bearing on whether or not it was closer to 5700 or 5200. Since most people agree on 5500 as about where it was, and personally when I drew a line, I believed it to be just over 5500, 5700 is the better estimate. </p>

<p>And if I remember correctly, the question did ask for an estimate.</p>

<p>That was a stupid question though, it shouldn’t be this debatable.</p>

<p>sorry guys.
yea,the slope is decreasing.</p>

<p>How the hell is the slope decreasing if the line is rising from left to right? Either our questions were different (highly unlikely) or you guys are over thinking the question (which is like grade 10 level math, not calculus)</p>

<p>hey does anyone remember what the two questions were to the two separate “4” answers?</p>
